A live check of the HTTP security-response headers supabase.com sends, the same class of signal as securityheaders.com. Present headers score points; missing ones do not.

What this is, and is not. This grade reflects only the publicly observable HTTP response headers of supabase.com, measured automatically. It is a hygiene indicator, one signal among many. It is not a security audit, not a penetration test, and says nothing about Supabase's internal systems, code or data handling. Many secure sites score below A because headers like Content-Security-Policy are commonly omitted.

What Supabase is used for

  • Postgres database hosting
  • Auth and user management
  • File storage
  • Instant APIs for apps
